Ann: Large Kimberlitic Signature Defined at L259, page-70

LARGE KIMBERLITIC SIGNATURE DEFINED AT L259 -
Gravity survey confirms a well-defined 110 hectare kimberlitic signature at the high-priority L259 directly beneath Mining Block 8 where Lucapa has been recovering large and valuable alluvial diamonds


 Gravity survey results from the high-p riorityL259 kimberlite at Lulo have identified a large and well defined kimberlitic signature which covers a known area o f110 hectares (~1.1km 2) and remains open to the south-west.
 The L259 kimberlitic signature sub crops directly beneath the Mining Block 8 area and is adjacent to Mining Block 6 where Lucapa has already recovered a combined total of 72 large special diamonds of up to 133 carats.
Gravity survey being extended to the south-west to fully define the extent of the L259 kimberlitic signature.
 Ground-based electromagnetic (EM ) survey on going at L259 to assist in modelling the signature geology–results
and interpretation expected in February 2016 Drill rig due to arrive in Angola in February 2016.
Once on site, this rig will commence drilling the outer rim of L259 to identify any near-surface kimberlite material,
which may be suitable for bulk sampling to determine diamond content.

Lucapa Diamond Company Limited (ASX:LOM ) (“Lucapa” or “the Company”) is pleased to announce the results of the gravity survey carried out at the high-priority L259 kimberlite at the Lulo Diamond Project in Angola.
The gravity survey has successfully identified a large and well-defined kimberlitic signature which covers a knon area of approximately
110 hectares (1.1km 2) and appears to extend beyond the survey grid boundaries to the south-west.
Significantly, the kimberlitic signature defined in the gravity survey envelops most of Mining Block 8 an d is adjacent to Mining Block 6,
where Lucapa and its partners have been recovering large and valuable alluvial diamonds on a regular basis.
To date, Mining Blocks 8 and 6 have produced 72 special diamonds (individual stones weighing > 10.8 carats) from mining and
exploration activities, including a 133 carat compound diamond and a 131 carat D-colour Type II a gem .

Lucapa Chief Executive Stephen Wetherall said the gravity survey results provided further evidence that L259 could be the primary
kimberlitic source of the alluvial diamonds from Mining Block 8- and possibly also those slightly down stream at Mining Block 6,
which has in recent weeks produced a number of large special diamonds of up to 133 carats.
This view is supported by the large and angular shape of the diamonds being recovered, larger average stone size recoveries and the
concentration of kimberlite minerals being recovered from the area.
Mr. Wetherall said:
“We are extremely pleased with these gravity results, which build on the kimberlite pitting program carried out earlier resulting in L259 being elevated to our highest priority kimberlite target. It is significant that the pits we recovered kimberlite material from in that pitting program sit within the L259 kimberlitic signature defined by the gravity survey.”
